This paper presents an approach to achieve User Model (UM) interoperability exploiting Web Service technologies for syntactic interoperability, and Semantic Web languages for semantic interoperability, together with negotiation techniques based on dialogue. We propose a SOA-based framework where a central UDDI registry, enhanced with UM specific capabilities, is used to support and promote the ...

The generation of Semantic Web services is a complex and error prone process. CODE, the system that we intend to demo, is an Integrated Development Environment that supports the developer through the whole process from the Java generation, to the compilation of OWL-S descriptions to the deployment and registration with UDDI.

A major problem for a grid user is the discovery of currently available services. With large number of services, it is beneficial for a user to be able to discover the services that most closely match their requirements. This report shows how to extend some concepts of UDDI such that they are suitable for dynamic parameter based discovery of grid services.

A web services based architecture for Language Resources utilizing existing technology such as XML, SOAP, WSDL and UDDI is presented. The web services architecture creates a pervasive information infrastructure that enables straightforward access to two kinds of Language Resources: traditional information sources and language processing resources. Details about two practical implementations of ...

Using search engines (e.g. Google), service registries (UDDI), peer-to-peer networks, service portals, and various other sources, Web service interfaces can efficiently be searched. In order to find out relevant Web services, clients have to dedicate extreme amount of time to surf through available service resources and be capable to distinguish between services that share 1 / 4

In order for Web services to be able to fully exploit the advantages of dynamic binding, requesting agents must be given a way to select the most ”convenient” service at invoke time. Current techniques do not address the problem of selecting services that best fit a requester’ needs. In this paper, we propose an extension of the UDDI specification in order to provide and exploit predictions abo...

We analyze the features of knowledge management in the Virtual R&D Organizations (VROs) and the features about the Service Oriented Architecture (SOA) in this paper. The application of SOA in knowledge management in VROs is further discussed. We process the registration, matching, and the construction of the UDDI in the knowledge service of VROs with SOA. Finally, we present a framework for the...

To improve popular services discovery mechanism (UDDI mainly), we propose an agent-based services discovery mechanism. In this mechanism, services information is stored in distributed servers that are regarded as independent agents. These servers are joined into a tree structure; and then, a recursive algorithm was used to distribute searching request over the whole tree. Based on this conditio...

Web-based simulation requires the convergence of simulation methodology and WWW technology (mainly Web Service technology). The fundamental concept of web services is to integrate software application as services. Web services allow the applications to communicate with other applications using open standards. We are offering DEVS-based simulators as a web service, and they must have these stand...
